I'm starting to dislike having sex w my boyfriend :(

Talia • 20 years old
me (19) & my boyfriend (21) have been dating for almost 8 months now . we have a long distance relationship & see each other about 2 weekends out of the month . since the first time we had sex , I've been slowly introduced to some of his fetishes that I don't necessarily like . such as , he has a serious obsession with feet & tickling me . like seeing my feet , licking my feet , sucking my feet , putting lotion on my feet , sending pictures of my feet , everything that has to do with my feet he is turned on by it . the feet thing isn't so bad , but his obssession with tickling me is what really gets to me . he gets turned on hearing me laugh so he tickles me ALL the time . like every once a while us playing around is fine but tickling me on the train , out walking & even during sex is not okay to me . I like to be caressed &  rubbed during sex & he doesn't do much of that even when I voiced it to him that I like that . instead he does what he wants to do which is tickling me suddenly in our most heated sessions every five minutes which instantly turns me off & I lose my desire for sex . I've told him several times to stop tickling me & that I hate when he does that during sex & he always just gets upset with it & ask why I can't just be submissive to him . then he continues to do it anyway the next time I'm with him . I love my boyfriend very much & I want to stay loyal to him but I can't help but think about how much I'm unsatisfied by him & think about what it's like to possibly have sex with someone else 😕😕 someone please tell me what I should do . I apologize for this being so long
